JAMES W. SMALLMAN, OF NUNEATON, ENGLAND.

HAULAGE-CLIP.

To all whom it may concern:

Be it known that I, JAMES NlLLIAM SMALLMAN, a subject of the King ofGreat Britain and Ireland, of Nuneaton, in the county of Warwick,England, have invented an Improved Haulage-Clip, of which the followingis a specification.

This invention relates to haulage clips of the kind described andclaimed in the specification to Letters Patent No. 7 28,421, dated 19May, 1903.

The accompanying drawings will now be referred to.

Figure 1 is a side elevation of the new model clip. Fig. 2 is a verticalsection on the line w w in Fig. 1 (looking in the direction of thearrow) the coupling with its pin and cotter being omitted. Fig. 3illustrates the inner surface of the left-hand shell. Fig. 4C is asimilar view of the right-hand shell. Fig. 5 is a side elevation of thesinglecoil hooked spring. Fig. 6 is an end view of that spring. Fig. 7is a vertical section of a clip having shells with wider jaws for largerropes; the hooked spring being double-coil instead of single-coil.

In the kind of clip cited above as having been patented in 1903, aspiral spring between the shells encircles the connecting bolt. As thepressure of the spiral spring is distributed all around that bolt, thejaws of the shells have only a slight tendency to open. According to thepresent invention, the whole or most of the force of a spring is appliedbelow said bolt; thus giving the jaws a strong tendency to open. Asinglecoil or double-coil spring made of fiat wire with hooked ends ispreferred. The hooked ends of the spring run parallel or nearly so forabout 60. Each shell has a recess for one of the hooks of the spring.The spring surrounds the connecting bolt; the ends of the springpressing against the shells just above the jaws. The spring, thoughhaving great freedom of movement, is well supported owing to therecesses for the hooks not coming opposite one another.

R is the right-hand shell.

L is the left-hand shell.

A. is the square-headed bolt which is turned for adjusting the clip.

a is the bearing-collar and a the bearingnut.

Specification of Letters Patent.

Application filed April 6, 1907.

Patented Nov. 23, 1909.

Serial No. 366,837.

B is the lever with its trunnion-peg I).

C is the pivoted catch that locks the lever B.

D is the coupling and (Z the pin by which it is attached to the clip.

E and E are liners riveted in the jaws 7a and Z.

f and f are the holes for the trunnionpeg b.

H and H are the inclines for the head of the lever B.

h and 72, are stops.

K is a single-coil spring with ends 70 and 7.2 that lie opposite eachother in order to keep the jaws n and Z parallel or nearly so. Thespring K has hooks m and m In the shell B there is a recess N that takesthe hook m; N being a recess in the shell L for the hook m 0 is a hookeddouble-coil spring engaging with recesses in the shells R and L.

A is a bolt with a Tshaped head.

a is a deep bearing-collar.

A is the hexagonal nut that is turned for adjustment.

lVhat I claim as my invention and desire to secure by Letters Patentis 1. A haulage clip comprising a pair of rocking shells, a boltconnecting the shells, a lever acting between said shells and a springthat exerts substantially the whole of its force below the bolt, asdescribed.

2. In a haulage clip, the combination, with a pair of rocking shells, abolt connecting the shells and a lever acting between said shells, of aspring having hooks that enter recesses in the aforesaid shells,substantially as set forth.

3. In a haulage clip, the combination, with a pair of rocking shells, abolt connecting the shells and a lever acting between said shells, of asingle-coil spring having ends that lie opposite each other below thebolt and press against the aforesaid shells, keeping the jawssubstantially parallel, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
